A shovel includes a lower traveling body, an upper turning body turnably mounted on the lower traveling body, a cab mounted on the upper turning body, an attachment attached to the upper turning body, a hardware processor, and a display device. The hardware processor is configured to move the end attachment of the attachment relative to an intended work surface with the ground being pressed with a predetermined force by the working part of the end attachment, in response to a predetermined operation input related to the attachment. The display device is configured to display information on an irregularity of the ground.
1. A shovel comprising:
a lower traveling body;
an upper turning body turnably mounted on the lower traveling body;
a cab mounted on the upper turning body;
an attachment attached to the upper turning body;
a hardware processor configured to move an end attachment of the attachment relative to an intended work surface with a ground being pressed with a predetermined force by a working part of the end attachment, in response to a predetermined operation input related to the attachment, and to record an area of the ground subjected to work by said moving the end attachment; and
a display device configured to display information on progress of the work and information on an irregularity of the ground based on the recorded area of the ground subjected to the work by said moving the end attachment.
2. The shovel as claimed in claim 1 , wherein the hardware processor is configured to derive the information on the irregularity of the ground from a change in a posture of the attachment during of said moving the end attachment relative to the intended work surface.
3. The shovel as claimed in claim 1 , wherein the hardware processor is configured to calculate an amount of soil to fill in a depression of the ground.
4. The shovel as claimed in claim 1 , wherein the display device is configured to display the information on the irregularity of the ground in association with construction drawing information.
5. The shovel as claimed in claim 1 , wherein the hardware processor is configured to execute feedback control of a pressing force or feedback control of a boom differential pressure that is a pressure difference between a boom rod pressure and a boom bottom pressure.
6. The shovel as claimed in claim 1 , wherein
the predetermined force is a force at a time when a boom differential pressure reaches a target differential pressure, the boom differential pressure being a pressure difference between a boom rod pressure and a boom bottom pressure, and
the target differential pressure changes according as a posture of the attachment changes.
7. The shovel as claimed in claim 1 , wherein
the predetermined force is a force at a time when an arm differential pressure reaches a target differential pressure, the arm differential pressure being a pressure difference between an arm rod pressure and an arm bottom pressure, and
the target differential pressure changes according as a posture of the attachment changes.
8. The shovel as claimed in claim 1 , wherein the information on the irregularity of the ground is information on a surface of the ground formed when the ground is pressed by the predetermined force by the working part.
9. The shovel as claimed in claim 1 , wherein the display device configured to display an image regarding the irregularity of the ground over an image regarding the progress of the work.
10. The shovel as claimed in claim 1 , wherein the display device configured to display the information on the progress of the work, the information on the irregularity of the ground, and an image representing the shovel including the attachment on a same screen.
11. A shovel comprising:
a lower traveling body;
an upper turning body turnably mounted on the lower traveling body;
an attachment attached to the upper turning body; and
a hardware processor configured to move an end attachment of the attachment relative to an intended work surface with a ground being pressed with a predetermined force by a working part of the end attachment, in response to a predetermined operation input related to the attachment, and to output an alarm in response to determining that the ground is not formed according to the intended work surface.
12. The shovel as claimed in claim 11 , wherein the hardware processor is configured to obtain information on an irregularity of the ground.
13. The shovel as claimed in claim 11 , wherein the hardware processor is configured to control a position or speed of the working part in a same direction as the intended work surface.
14. The shovel as claimed in claim 11 , wherein the hardware processor is configured to press the working part with the predetermined force in a direction perpendicular to the intended work surface.
15. The shovel as claimed in claim 11 , wherein the hardware processor is configured to move a bucket relative to the intended work surface with the ground being pressed with the predetermined force by a back surface of the bucket.
16. The shovel as claimed in claim 11 , wherein the hardware processor is configured to move a bucket relative to the intended work surface with the ground being pressed with the predetermined force by a back surface of the bucket and a predetermined angle being maintained between the back surface of the bucket and the intended work surface.
17. The shovel as claimed in claim 11 , wherein the hardware processor is configured to move the end attachment relative to the intended work surface while keeping the ground pressed with the predetermined force by the working part, in response to the predetermined operation input related to the attachment.
